摘要： An on-vehicle DC/DC converter transforms high-voltage electric power originating from an on-vehicle high-voltage source to low-voltage electric power at a regulated voltage level. The low-voltage electric power is distributed by a low-voltage bus. A method for operating the DC/DC converter includes monitoring a state of charge and a temperature of a low-voltage battery connected to the low-voltage bus, setting a DC/DC converter command to a nominal voltage level as a function of the state of charge and temperature of the low-voltage battery, monitoring a total low-voltage electric load, and adjusting the DC/DC converter command to a minimum low-voltage reference voltage when the vehicle is operating below a predetermined speed and the total low-voltage electric load is greater than a predetermined load.
